Have you got comms to the other modules in the car?

No not had any response from the car just says initialising ecu and no response...

What do you get when you "Test Interface" ?

You might be better testing it on the bench and scoping data lines for K and CAN.

Checking Interface...

Disable SWCAN...
Switched to DWCAN...
Pin #6,#14 switched to HSCAN...

Checking Interface...

also saying no power from car but red and green lights both on...

Disable SWCAN...
Switched to DWCAN...
Pin #6,#14 switched to HSCAN... the most ive had is the ignition lights flashing while checking interface... bit of a novice so not sure what settings etc to go for...any pointers would be much appreciated thanks

Dunno about W10. Tried it for a short while and binned it. Total shit for diag stuff. Half the time defender interferes and screws USB comms and u cant switch it off. Try flashing an ecu when defender decides it wants to update half way thu and see what happens.

W7 x86 or XP (or W7 x64 if u specifically need it) with no AV best for any diag sw especially with opcom 139 145 154. If W7 theres a few bits to disable like UAC, defender, notifications, USB power mode etc. etc.

Dunno about yr problem tho. Is it just on that car? Have u measured voltage on obd socket and scoped data lines? (pins 6 and 14). If signals there then try another interface. They are cheap enough.
